To all whom it may concern.-

Be it known that we, JOsHUA R. EDDY and RICHARD F. HADLEY, citizens of the United States, residing at Slicker, in the county of Tyler and State of West Virginia, have invented a new and useful Casing-Head for Gil- Wells, of which the following is a specification.

This invention relates to casing-heads for oilwells, and has for its object to provide improved means for catching the flow of oil when the operating mechanism is withdrawn from the well-casing A further object of the invention is to provide a casing-head having a cut-off valve pivotally mounted therein and movable to operable gosition when the tools are withdrawn, there y to deflect the flow of oil throu h a series of discharge-openings into a suite is oilsaver or other receptacle designed to receive the same.

A still further object is to generally improve this class of devices so as to add to their utility and durability, as well as to reduce the cost of manufacture.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, propon tions, and minor details of construction ma be resorted to within the scope of the appen ed claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of a casing-head constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view taken on the line 2 2 of Fig. 3. Fig. 3 is a similar view taken on the line 3 3 of Fig. 1.

Similar numerals of reference indicate cor responding parts in all the figures of the drawlhe device consists of a tubular body portion comprising a relatively stationary section 5 and a movable section 6, said sections being provided with laterally-extending reinforcin -flanges 7 having coincident openings formed therein for the reception of clampingbolts 8. One end of the body portion is extended to form an annular flange 9, having setscrews 10 threaded therein for engagement with an oil-saver or other suitable re ceptacle designed to receive the oil, while the opposite end of said body ortion is threaded at 11 for connection with t e adjacent section of the well-casing.

The ivoted section 6 is provided with a reduced which is curved or rounded, as indicated at -13, and seated in a correspondingly-shaped socket 14, formed in an enlargement 15 on the stationary section 5, the sections being pivotally united by means of a bolt 16, passmg through the enlargement and engaging the tongue, as shown.

The interior walls of the movable section 6 are provided with a circular depression or recess 18, which forms a seat for a valve 19 when the latter is in open position, said valve being ada ted to engage an annular stopcollar or ange 20, extendin inwardly from the Walls of both sections w en the valve is in closed or operative position.

The valve 19 is preferably circular in form and provided with a reduced shank 21, the end of which is seated in a recess 22, communicatingwith the recess 18 and rigidly secured to a rock-shaft 23, journaled in a suitable bearing-plate 24,fastened to the movable section 5. The rock-shaft is extended a short distance beyond the plate 24 and provided with an operating-handle 25, by means of which the valve may be moved to operative and inoperative ositions.

The walls of the stationary and movable sections are provided with a plurality of threaded discharge-openings 26, through which the oil is discharged when the pum operating mechanism is withdrawn and t e valve 19 is in closed position, the oil being preferably conducted through suitable pipes threaded in the o enings 26 and communieating with the oi -saver or other suitable rece tacle designed to receive the same.

en the pump is in operation, the valve 19 is in open or inoperative position, as shown by dotted lines in Fig. 3 of the drawings, thereby permitting free vertical movement of the sucker-rod or operating-tools within the well-casing. When the operating mechextension or tongue 12, the end of anism or tools are withdrawn, however, the valve is moved to closed position in engagement with the stop-collar by turning the operating-handle to the position shown in full lines in Fig. 3, thereby cutting oil the flow of oil at the top of the casing and deflecting the same through the dischargeo ening, the oil being conducted through suita le ipes to an oil-saver or other receptacle, as be ore stated. It will thus be seen that the flow of oil, which usually occurs when the operating-tools are withdrawn from the casing, is effectually saved, thus enabling the operator to utilize the entire output of the wel By havin the casing-head formed in sections, one 0 which is movable laterally to open position, said movable section may be swung outwardly by releasing the clampingbolts 8 to thereby permit the ready insertion and removal of the cut-off valve and also to ermit the removal of any accumulations of 'oreign matter within the head.

Having thus described the invention, what is claimed is 1. A tubular-casing head comprisingstationary and movable sections rovided with discharge-apertures, and a va ve carried by one of said sections and adapted to close the adjacent end of the casing-head.

2. A tubular-casing head comprising stationary and movable sections having discharge-apertures formed in the side walls thereof, and a valve carried by the movable section for closing the adjacent end of the easing-head.

3. A tubular-casing head comprisin stationary and movable sections provide with lateral discharge-a ertures, a rock-shaft carried by the mova 1e section and provided with an operating-handle, and a valve secured to the rock-shaft and adapted to close the adjacent end of the casing-head.

4. A tubular-casing head comprising stationary and movable sections provided with lateral discharge-a ertures, a seating-recess formed in the mova le section, a valve seated in said recess and adapted to close the adjacent end of the casing-head, and a weighted lever secured to the valve for operating the same. 7

5. A tubular casing comprising stationary and movable sections provided with lateral discharge-apertures, one of said sections being provided with a seatin -recess having an openin communicatin t erewith, a valve seated in the recess an provided with a reduced shank movable between the walls of said opening, a rock-shaft secured to the valve and provided with a handle for actuating the valve to close one end of the casing-head, and means for clamping the sections together.

6. A tubular-casing head eomprisin a stationary section having a socket forme therein, a movable section provided with a reduced extension pivotally mounted within the socket, a valve ivoted to the movable section and adapted the casing-head, there being a lurality of discharge-apertures formed. in t e walls of said sections and means for clamping the sections together.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two Witnesses.
